dirge (n.)

early 13c., dirige (current contracted form is from c. 1400), from Latin dirige "direct!" imperative of dirigere "to direct," probably from antiphon Dirige, Domine, Deus meus, in conspectu tuo viam meam, "Direct, O Lord, my God, my way in thy sight," from Psalms v.9, which opened the Matins service in the Office of the Dead. Transferred sense of "any funeral song" is from c. 1500.
